Guys I was just wondering... I'm about to start working up some 30-06 loads w/ some 4831 and some 180 bergers... and I'm seeing a good bit of case length differences. ALMOST all of my once fired 7mm RUMs are 2.850, with a few @ 2.845s. These 30-06 cases are ranging from 2.490-2.509. All sized with the same dies, now not all were fired from the same gun though. I never even purchased a case trimmer, b/c of the consistency of the once fired 7mmRUM brass. Now to me just looking @ the case trimmers it looks like its going to be hard to get every single case the same lenght without repeatedly checking, and IF you do slip up and cut one a little too much it looks like your gunna start BACK over... IF you have racked up about 50-60 brass, I guess you can set that case out... BUT I like to work in even numbers! lol I'm gunna order myself a case trimmer this week anyway.
